The biggest masonry bit at the hardware store is 1". I tried a hole saw meant for wood, figuring it was about 5 bucks and thought it'd might be a one-time use thing - I can see now why it was meant for wood. I got maybe an 1/8" deep and the points were already ground down pretty well. I tried drilling a bunch of little holes and then tried chiseling it out, but that just broke the brick. My current plan to to try to get the brickyard to do it. Any ideas? I have a RotoZip, but I'm not sure if that's the right tool.
